New TV-B-Gone Case Style

TV Disabler

Have you ever found yourself in a situation where you wanted to talk about something important or just simply wanted some peace and quiet while enjoying your drink and a damn TV wouldn’t shut up? Chances are you have. But from now on, you can use this little gadget to silence those TV sets that bother you with loud, uninteresting stuff. You can carry it in your pocket and you can surely have a laugh using it.

Humorously named TV-B-Gone, this TV Disabler can make some annoying situations quite entertaining. The TV-B-Gone can turn off most of the TV sets available, while having about the same size as a universal remote control. It is a nifty little kit made by Adafruit and it is available for purchase for $19.50. It possesses an Atmel ATTINY85V-10-PU programmed microcontroller, 4 IR LEDs used as emitters and a double AAA battery holder (you can find a complete parts list in the link).

The TV Disabler must be pointed at the TV you wish to quiet down. It has a single button that must be pressed and then it starts to transmit its signal using codes that are stored in its memory for all major TV brands. It takes about 2 minutes to send all the codes, but most TV sets will turn off. The TV Disabler also has a green LED that starts glowing once the device is transmitting.

Since the original kit from Adafruit doesn’t have a case, you can make one like the one in the picture above. This project uses a modified Miniature General Purpose ABS Box 1551 Series from Maplin Electronics Ltd. You will have to make 2 holes, one for the button, and the other for the LED. Putting it all inside the box may be tricky, but once you get it right you will have the TV-B-Gone ready and waiting. And you can say goodbye to those noisy TVs disturbing you.

Micro Pong game

micro pong game

Looking at the schematic and the firmware this is probably the most compact pong game project, the PIC12F675 has only 6 pins which can be used, an very small flash and ram resources, only 64 byte of RAM!

The TV output is PAL, no other format is supported, the game is controlled with two consoles made of potentiometer and push button, both dual and single player mode is available with two speed option, the small hardware has even an audio output which sends outs the beeps.

The source code is written in assembler language and highly optimized yet reasonable commented, but I don’t recommend reverse engineering it, it is easier to read the authors documentation.

This project shows the real power of assembler language if used properly, this doesn’t mean that every project should be implemented in assembler language, but if space and speed requirements are scarce, then it’s the only solution.

Wireless Controlled Lightdimmer Using TV Remote Control

The goal of this project was to build a normal dimming lamp that is also controlled wireless with a tv remote control. When you switch the power on there will follow a soft-start till the lamp burns at the previously adjusted dim level. With the P+ and P- button from a system at choice you can adjust the maximum and minimum dim-levels and with the ‘1’ button the start-up brightness. The next time when the 230V power is switched on the lamp starts up at the adjusted dim-level.

Tv remote jammer

tv remote jammer

    If you are planning to disturb your friends this is the way you should do it, because you will get immediate results. You can build this project with a few cheap parts. The tutorial is released by the guys from Instructables. Here is what they say about it:
How does it work ?

This is a pretty simple concept. When you press a button on a remote control for a TV, stereo or other IR device, it creates a series of pulses which the receiver in the target device; in this example, a TV, decodes into the corresponding function. This frequency is around 35-40kHz. To confuse the receiver, this jammer sends out a steady stream of binary code (1’s an 0’s) at the same frequency, but contains no information to decode. The receiver basically sits there and does not respond at all and the real information cannot get through to it as long as the jammer is on. Voila! You’ve ‘jammed’ your TV remote

Here is the link to the tutorial page Link.
